Ultrastructure of chondrocytes in osteoarthritic femoral articular cartilage.
BACKGROUND Osteoarthritis (OA) is a common problem in elderly, but it is not an inevitable feature of ageing. About 80-90% of individuals of both sexes have radiographic evidence of OA by the time they reach an age of 65. But not all of them have the symptoms like pain and decreased joint motion. OBJECTIVE The objective of the present study was conducted to find out whether the osteoarthritic...
متن کاملAlloreactivity and immunosuppressive properties of articular chondrocytes from osteoarthritic cartilage.
PURPOSE To determine whether articular chondrocytes derived from osteoarthritic knee joints could evoke alloreactive proliferation of peripheral blood mononuclear cells (PBMC) and inhibit mitogenic activity of polyclonally activated CD4+ major histocompatibility complex (MHC) class II- restricted T cells in vitro. METHODS Osteoarthritic cartilages of 17 patients aged 61 to 85 years were harve...
متن کاملEvaluation of CD98 Expression in Normal and Osteoarthritic Human Articular Chondrocytes
Background: Recent studies have provided evidence that integrins play roles in recognition of mechanical stimuli and its translation into a cellular response. Integrin signaling may be regulated by a number of mechanisms including accessory proteins such as CD98 (4F2 antigen). Objectives: To determine CD98 expression by human articular chondrocytes and its involvement in human articular mechano...
متن کاملDifferential Immunohistochemical Expression Pattern of Galectin-3 in Normal and Osteoarthritic Human Articular Cartilage
Background: Previous studies have shown that Galectin-3, a member of lectin family, is expressed in developing cartilage in mouse embryo and also in growth plate of long bones. Objective: In the present work, the expression pattern of Galectin-3 in normal and various grades of osteoarthritic (OA) human articular cartilage has been studied. Methods: Using immunohistochemistry and standard we...
متن کاملSerotonin-stimulated phospholipase A2 and collagenase activation in chondrocytes from human osteoarthritic articular cartilage.
We have previously described several receptors on the chondrocyte membrane. In an attempt to further characterize the coupling mechanisms of serotoninergic receptors, here we examined the involvement of serotonin in the phospholipase A2 activity. Serotonin dose-dependently stimulated phospholipase A2. This activation enhanced collagenase type II activity and had no effect on proteoglycanase act...
